This film is quite interesting. Most of what I would like to say has already been said. It certainly isn't one of the best Korean movies I've seen.

My main complaint is that the motivation of the murderer is never made clear. Perhaps this is my fault and I missed at the hints, but I kept on wondering why the murderer would kill these people and rip up their bodies. Still, it soon seemed quite obvious who the murderer would be (my wife guessed after about 20 minutes). And this was the largest problem with the film: the film is beautifully shot, well acted, well told, but you still can't work out the murderer's motivation or empathise with her.
